Products
Special function fluorocarbon material
As a kind of functional carbon material, fluorocarbon materials have many specialty performances. They have been widely used in solid lubrication, corrosion protective and antifouling coating, flame retardant material, moderator of nuclear reactor and Li-CFx batteries due to the merits of extremely low surface energy, excellent chemical stability, outstanding heat endurance and super theoretical specific capacity.
The large scale demonstration production line has been completed in 2016, many productions have been produced, including fluorographite, fluorographene (powder, flake and etc.), fluorographene substrate, fluorinated carbon nanotubes, fluorinated carbon black, fluorodiamond, fluorinated carbon fiber, fluorocoke, fluoropitch and fluorographene / PANI composite, etc. And we can customize various fluorinated products of different fluorination ratios for customers.
Lithium-fluorocarbon battery (Li-(CFx)n)
Lithium-fluorocarbon battery (Li- (CFx) n) with cathode material of (CFx) n and anode material of lithium, which is the best primary battery system at present. The theoretical energy density of the Li- (CFx) n battery system is up to 2180Wh / kg, which is the battery system with the largest theoretical specific energy in the primary batteries. Lithium-fluorocarbon batteries consist of button, cylindrical and soft package batteries.
With high specific capacity and high energy density, fluorocarbon batteries are easy to be miniaturized.
Fluorocarbon material has excellent thermal stability and does not decompose at high temperature (≤600 ℃), besides it does not crystallize at low temperature, so the capacity retention rate of Li- (CFx) n battery is high, the working temperature range of Li -(CFx) n battery can achieve to -40 ~ 125 ℃ after the battery is improved.
The discharge performance of Li- (CFx) n battery is excellent, the working voltage is as high as 3V. At the same time, when the battery is working, the fluorocarbon is converted into lithium fluoride and carbon that can conduct electricity, and the internal resistance does not increase. The discharge plateau is stable, and the working voltage can be stable until the end of discharging.
Li- (CFx) n battery is very stable, no matter in the process of using or in the condition of normal storage, its self-discharge rate is very low, ≤1%, its shelf life is more than 10 years.
The excellent chemical and physical stability of the fluorocarbon ensures the safety of the Li- (CFx) n battery. It is still very safe in the case of short circuit, extrusion, collision, over discharge and high temperature.
During the process of production, using and rejection of batteries, there is no heavy metals involved.
Materials for Semiconductor
Semiconductor manufacturing is a process that the electronic component are manufactured on silicon semiconductor, while the electronic components are made up of sophisticated integrated circuit, the process mainly includes manufacture of wafer, manufacture of IC with wafer (manufacture of thin film, photolithography, etching and ion implantation), metallization process, wire bonding, packaging and test. There are some materials used in the process of semiconductor manufacturing, semiconductor materials mainly include silicon, germanium and gallium arsenide. Photoresist used in the photolithography is a kind of photosensitive material which is mixed with photosensitizer, resin and solvent. Insulating material, aluminium and albronze are used in the metallization process, gold thread with diameter of 0.025mm is used in the process of wire bonding. Finally epoxy resin and ceram material are used in the process of packaging . Plasma etching of integrated circuits is a crucial process in se miconductor manufacturing. With the development of semiconductor industry technology and the refinement of component in integrated circuits, plasma etching technology has been widely used in semiconductor manufacturing process due to its advantages such as anisotropic etching, process compatibility and few etching residues. The etching gas manufactured by our company is usually fluoride gas, including nitrogen trifluoride, perfluorobutadiene, hexafluoroethane, octafluoropropane, etc.
